Intermittent exception after logging into Abp #3073

ABP Commercial / Blazor Server / EF Core

Hi, we occasionally receive the exception below right after signing in. When we click 'Reload' in the generic blazor error notification at the bottom of the page, the site loads correctly.

Thanks in advance, Brian
